About this image

A BAA and AAVSO alert notice had highlighted an expected (super)outburst of YZ Cnc.

At an estimated mag around 12.3 (Gary Poyner, et al) I thought I'd have a go at capturing a spectrum.

Two runs with a few hours in between shows a rise in flux to outburst. Not particularly good SNR but starting to see results.

These spectra aren't normalised. That's just the result (using a hot blue star to calibrate) and shows the flux domination of the disc in outburst with a few emission lines (?). Not sure whether there's enough real signal to extract meaningful information but it's another step forward.

Captured and processed in Demetra and presented using BASS.
